Models (and Multipart Models) represent our fighting warriors, monsters and spell casters. All models are part of a Unit

ModelsModels represent our fighting warriors, monsters and spell casters. Everything that is standing on the same base is considered the same model (i.e. a dragon and its rider, or a cannon and its three crewmen, are considered a single model).

Multi-part Models
Models with more than one characteristics profile (such as a rider and its mount). Each part of such a model with its own characteristic profile is referred to as "part of model". I.e. an Elven chariot is a single model consisting of 5 parts (2 Elven horses, 2 Elven crewmen, 1 Chariot Carriage). A normal foot soldier is a single model consisting of a single part. Whenever a rule affects such a "model", all parts of the model will be affected unless noted otherwise.

Units
All models are part of a Unit. A Unit is either a group of models deployed in a formation consisting of ranks (along the width of the Unit) and files (along the length of the Unit) or a single model operating on its own. Whenever a rule, ability, spell and so on affects a Unit, all models in the Unit are affected. When forming a Unit, all models in the Unit must be perfectly aligned in base contact with each other and face the same direction. All ranks (except the last one) must always have the same width. The last rank can be shorter than the other ranks; if so, this is called an incomplete rear rank.
